Output of the SOA measured in the electrical domain depicting the intermediate frequency signal associated with the 371.1 GHz beat-tone from the mode-locked laser under investigation. In the inset is depicted the intermediate frequency of a 909.5 GHz beat-tone signal. Experimental measurements are shown in and Lorentzian fitting in continuous line.
